I liked Dirt 2 so much, I picked this up, and it's pretty damned cool. It's a lot like Dirt 2 but with F1 cars. MP is supposed to be pretty good. Reading through the Codemaster forums, there seems to be a pit stop bug where if you are in the lead and you pit ahead of the racers behind you, you cannot leave the pits until the other racers pass by the pits. This is in MP only as far as I know, but CM says they are working on a fix for it.
